EDWARD WHITE, OF PHILADELPHIA, PENNSYLVANIA.

nrrrusnn FOR HEADLIGHTS.

Application filed September 20, 1924. Serial No. 738,757.

To all whom it may concern."

Be it known that I, EDWARD WHITE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Diffuser for Headlights, of which the following is a specification.

This invention, generally stated, relates to headlights for motor vehicles and the like and has more especial relation to an attachment therefor to procure focusing of the headlights to meet legal requirements.

The leading object of the present invention is to provide a device of this character which is of simple, eflicient, and comparatively inexpensive construction which may be readily applied to existing headlights in a few moments time by unskilled mechanics without the necessity of changing the light bulb or lamp or requiring any special make of lens.

A further object resides in the provision of general details of construction and arrangement of parts for attaining the results sought by the leading object.

The invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1, is a view of the underside of the diflusing device embodying the invention.

Fig. 2, is a view thereof in front elevation; and

Fig. 3, is a view of the diffusing device in cross section shown in application to a headlight the latter being shown by dot and dash lines.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring to the drawings the device of the invention is shown as comprising a horizontally arranged, thin, fiat plate designated by the numeral 1. This plate is preferably made of metal thin enough to be bent for a purpose to presently appear. The'plate 1 is provided with a straight front edge designated 2. The rear portion ofthe plate 1 is curved as at 3 to snugly fit against the rear wall of a headlight reflector which, as shown in Fig. 3, is designated 4;. The plate 1 terminates at its rear in a downwardly extended finger 5 which is vertically and laterally curved to snugly fit against the rear wall of the reflector l, as clearly shown in Fig. 3. The finger 5 is provided with a bolt hole 6 and with an opening 7 which opening is provided to permit of the finger 5 engaging over the lamp socket 8 and bulb or lamp 9 without disengaging said bulb or lamp from its socket. The lamp socket is carried by the usual reflector casing 10. 11 designates a bolt for passing through hole 6 of the finger 5 and penetrating the reflector 4 in order to secure the diffusing device to place. With a device of the character stated positioned as shown in Fig. 1, all rays of light from lamp 9 having the tendency to be deflected upwardly at an angle are by the present device diffused by plate 1 and caused to project forwardly in a horizontal stream of light. The plate 1 being of thin, relatively yielding metal may be readily bent to obtain any desired angle in order to secure a desired or proper focusing of the headlight. The plate 1 is upon its under side highly polished in order to serve as a deflector. In view of the fact that the plate 1 is shaped at its rear to snugly hug the reflector 4 entirely therearound no rays of light from lamp 9 may pass to the upper part of the reflector. The front straight edge 2 of the plate 1 extends in a horizontal manner practically to the lens 12 so that all rays of light below plate 1 are necessarily maintained below said plate the advantage of which is readily apparent. i

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in Various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, What I claim as newand desire to secureby Letters Patent, is:

A device of the character stated comprising in combination a reflector casing provided with a lamp socket including a lamp, a

reflector through which said socket projects, a light diffuser comprising a horizontally arranged, thin, fiat plate having a straight,

front edge and a rear portion curved to snugly fit against the rear wall of the reflector said plate terminating at its rear in a dow w rd y extended finger apertured to engage over said lamp, said finger being curved Vertically and laterally to snugly fit against the rear Wall of the reflector and a boltfor detachably securing said finger to said rear wall.

In testimony whereof, I have hereunto signed my name.
